How to Care for the Plant

Water
In terms of moisture level in the soil, horsetail prefers a soil that is at least moderately wet. It can even grow in standing water up to a depth of about 4 inches. At the same time, it is also drought-tolerant. This tolerance for very wet and dry conditions makes horsetail uncommonly suited to rain gardens.
Fertilizer
In general, horsetail plants do not need particularly rich or fertile soil, so fertilizing often is not necessary. If desired, you can feed it with a slow-release plant food.
Sunlight
Horsetail is extremely adaptable to various light levels, growing in full sun to part shade, and even deep shade.
